Rain Drop

Classical Mechanics Level 2

The above is a depiction of rain drops falling on a car being driven at a speed of \(3\) m/s. If the angle of the rain drops on the car window is exactly \(45\)°, then what is the speed of the rain drops from a stopped observer's position? (Assume that the speed of the rain drops is constant and raindrops are falling straight down.)
